Jizo Statues in Kamakura, Japan.

Jizo statues in Kamakura, Japan. Jizo take care of the
souls of unborn children and those who died at a young age. Children “in limbo”
in Japan are said to go to a place called sai no kawara, where they must create
piles of stones into small towers. But every night the stone towers are
destroyed by demons, so the next day the children must make new piles of
stones. The making of these towers is to help their parents accrue merit for
their own afterlife.
